Detailed :

Bell type annealing furnace

The main process equipment of full hydrogen bell annealing furnace includes annealing furnace table, inner cover, heating cover, cooling cover valve station with supply discharge pipes. At the beginning of annealing, the workpieces to be annealed shall be stacked on the annealing furnace, the inner cover shall be hoisted. The cold sealing test shall be carried out on the hearth, inner cover system hydrogen inlet valve. After the test is successful, nitrogen purging shall be carried out, the heating cover shall be hoisted, then the heating cover shall be ignited. When the nitrogen purging meets the conditions, the nitrogen in the inner cover should be replaced by hydrogen purging. Start heating heating curve according to different materials for temperature control until the process requirements are met.

In the process of full hydrogen bell type annealing furnace, the cooling should start the heating cover which is still on the hearth. First, air should be blown into the heating cover, then the heating cover should be removed. Then the cooling cover is hoisted the air of the surrounding environment is sucked through the fan on the cooling cover to cool the inner cover. When the circulating atmosphere in the inner cover reaches the set temperature, the cooling hood fan should stop running. After a period of time, the spray cooling starts. When the temperature reaches the set value, the cooling is finished the cooling cover is removed. Then nitrogen purge is carried out to replace the hydrogen in the inner cover remove the inner cover. This process is completed.

Scope of application:

1. Bright annealing of precision alloy strip wire.

2. Annealing of steel castings forgings.

3. Annealing of finished silicon steel sheet.

4. Metal, non-metallic powder pressing parts sintering.
